Mirrored / Extended desktop and calibration
We are running Win 7 64bit with activstudio with a dual monitor PC (one 19" LCD and the IWB projector). Some teachers have this set to extended desktop and some mirrored (we should have never given them the choice!). When a teacher logs in and it switches from extended to mirrored or vise-versa the board needs recalibrating (presumably because the resolution has changed). Does anyone know of a way of allowing users to switch between desktop modes without having to recalibrate?
